' 6 Claims.

This invention relates to new and useful improvements invisible margin files, and is susceptible of a great variety of uses. One practical application of the invention, for example, would be in the convenient indexing and filing of stamps of various denominations and descriptions. v

The primary objectof the invention is to provide a visible margin file in which the respective cards or elements may be removably fastened together in the proper sequence by a novel flexible .strip and slot connection, whereby the desired visible top margin may be easily and readily obtained by a very simple method of manipulation. A further object of the invention is to provide a unique method of connecting the respective cards or elements of the file together, whereby the relative sliding movement of the cards re-- sulting in the desired top margin is not only uniform, but definitely pie-determined or prescribed.

Another object of the invention is to provide a visible margin file in which relative end-wise 'movement of the'respective cards is prohibited,

thus insuring the perfect alignment of the cards Still another object of the invention is to provide the flexible interlocking strips with preformed offset ends, which will prevent the latter from working out of placeand whereby the ends of said strips will not protrude or spring away from the front faces and bottom edges of the corresponding cards, but will lie perfectly flatwise' against the same.

Another object of the invention is to provide a visible margin file, in which any one or more of the cards or elements may be easily and readily removed'from the unit and entirely omitted or replaced, as desired.

Still yet another object of the inyention is to provide a visible margin file which is very simple and economical in construction and highly efiicient and durable in use.

With the foregoing and other objects in View that will appear as the nature of the invention is better understood, the same consists in the novel features of construction, combination and ar-. rangement of parts illustrated in the accompanying drawings and more particularly pointed out in the appended claims.

' In the accompanying drawings, which are for illustrative purposes only and are therefore not drawn to scale: 7

Figure '1 is a front elevation of a visible margin I file embodying my improvements.

Figure 2 is an end view.

Figure 3 is an enlarged detail fragmentary sectional view, with the respective cards spread apart at their upper margins to more clearly illustrate the construction. 1

Figure 4 is a vertical transverse section, taken on line 4-4 of Figure 3, looking in the direction indicated by the arrows.

. Figure 5 is a horizontal section, taken on line 5-5- of Figure 4.

Figure 6 is a similar view, of Figure '3.

Figure 7 is an enlarged detail fragmentary perspective view, showing the preformed ofiset end portions of the flexible interlocking strips and associated parts.

Figure 8 is a view similar to Figure 1, with the respective cards spread apart to disclose the visible top margins.

Figure 9 is an edge View of Figure 8.

taken on line 6-8 Figure 10 is an edge view of one of the cards once characters throughout the several views,,A

designates the front cover, B the back cover and C the respective cards interposed or arranged between the front and back covers aforesaid.

The front cover A is formed adjacent its bottom edge, with a pair of centrally disposed finger openings l, the purpose of which will presently appear, while the back cover B is formed at its upper edge with a central upwardly projecting tab 2, bearing the designation Stamps or' other suitable indicia. The cards C are formed at their upper left hand margins with the names of different countries, or other suitable indicia, as 3, and this memoranda is disclosed to view or rendered visible when the cards are. spread apart by. the file clerk or other interested 'person, as illustrated in'Figure 8 of the drawings.

As many cards may be utilized in one file or unit asdesired, and each card is of corresponding form or structure. Specifically, each card is composed of a rectangular oblong strip or piece "of card board or other like material, formed at its bottom edge with a longitudinally disposed fiap i, of uniform width. The flap extends the full length of the card and normally folds f0r-= wardly and inwardly and fits against the lower edge and back face of the next forward succeedlng card.

preformed offset end portions 8 which extend through the slots 8 of said flaps and the co-incident or registering slots 5 in the bottom edges of the cards and lit against the front faces of the latter, as illustrated more particularly in Figures 4, 6, and 7, of the drawings.

The particular structure of the preformed offset end portions 8 of the strips 1 is an important feature of'my invention by virtue of the fact that this special construction permits the ends of the interlocking strips to fit perfectly flatwise against the front faces of the corresponding cards, whereas, the ends of the aforesaid strips would otherwise protrude or spring away from the adjacent faces of the respective cards and interfere with or impede the free sliding movement thereof in obtaining visibility of the indicia or memoranda at the upper left hand margins of the cards.

The slots 6 of the flaps 4 correspond exactly in length with the width of the flexible interlocking strips 1, whereasthe length of the slots 5 in the bottom edges of the cards is greater than the width of said interlocking strips to allow for the necessary predetermined visible top margin. The first card and last card of the series of cards C are glued or otherwise secured to the inner faces of the front and back covers, respectively.

In practice, the respective cards of the file are spread apart or shifted to obtain the desired visible margin at the top by inserting the first two fingers of the right hand in the openings 1 of the front cover A and then grasping the tab 2 of the back cover B with the left hand and finally exerting a gradual pull in opposite directions. The file may be laid flat on thedesk, if desired, in performing the above operation.

The front face of each card C is provided with one or more transparent strips 9, which are preferably sewed or otherwise attached to the card at their bottom and end margins with their upper edges unattached or open, thus forming pockets l0 inwhich the stamps. or other material may be readily introduced or filed and as easily removed, if and when desired.

From the foregoing description taken in connection with the drawings, it is thought that the construction, operation and advantages of my in- I vention will be readily understood, without requiring a more extended explanation.

Various changes in the ,form, proportions and minor details of construction may be resorted to without departing from the principles or sacrificing any of the advantages of my invention, as defined in the appended claims.

Having described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. A visible margin file comprising a plurality of corresponding cards or elements having relative predetermined movement in one direction,

whereby uniform visible top margins may be obtained. each of said cards provided at its bottom edge with a flap and having long and short transverse registering slots formed in its bottom edge and said fiap, and separate longitudinally disposed fiexible interlocking strips arranged with their end portions extending through the aforesaid co-incident slots.

2. A visible margin file comprising a plurality of corresponding cards or elements having relative predetermined movement in one direction,

whereby uniform visible top margins may be ob-,

tained, each of said cards provided at its bottom edge with a fiap and having long and short transverse co-incident slots formed in its bottom edge and said flap, and separate longitudinally disposed fiexible interlocking strips of uniform width having preformed offset end portions extending through said co-incident slots and lying flatwise against adjacent faces of the corresponding cards:

3. A visible margin file comprising a. plurality of corresponding cards or elements having relative predetermined movement in one direction, whereby uniform visible top margins may be obtained, each of said cards provided at its bottom edge with a flap and having long and short transverse co-incident slots formed in its bottom edge and said flap, and separate longitudinally disposed fiexible interlocking strips of uniform width having preformed offset end portions extending throughsaid co-incident slots and lying-fiatwise against adjacent faces of the corresponding cards, the slots in the flaps formed by a continuation of the slots in the bottom edges of the cards and being of a length corresponding exactly with the width of the strips.

4. A visible margin file comprising a plurality of corresponding cards or elements having relative predetermined movement in one direction, whereby uniform visible top margins may be obtained, each of said cards provided at its bottom edge with a flap and having long and short transverse co-incident slots formed in its bottom edge and said fiap, and separate longitudinally disposed fiexible interlocking strips of uniform width having preformed offset end portions extending through said co-incident slots and lying flatwise against adjacent faces of the corresponding cards, the slots in the flaps formed by a continuation of the slots in the bottom edges of the cards and being of a length corresponding exactly with the width of the strips and the slots in the bottom edges of the cards being of a length greater than the width of the strips to allow the predetermined movement for the desired visible top margins.

5. In-a visible margin'file comprising a. plurality of cards having relative predetermined uniform vertical sliding movement, a flexible interlocking strip and slot connection between adjacent cards ofthe series, said strips being entirely separate and independent of the cards and havadjacent faces of the corresponding cards.
